This is from a exhibition called Body Worlds at California Natural History Museum. The artist Gunther von Hagens developed Plastination as a way to persevere body parts of animals and humans. First done in 1977 it is a process that replaces fat and water in the body with various enduring plastics. What is amazing is Plastination yields specimens that can be touched, do not decay or smell but amazingly the tiniest of body structures are preserved. Yes, all of his work is done on real bodies. His vision is to educate all on various effects of living, disease and environmental stress. This photo shows the effect of smoking. He never will run out of things to do. Currently their is 16, 000 humans who already have donated their bodies. You can too if you look up Body Worlds there is a donation form. He also has branched out and is doing animals. Currently he is working on a Blue Whale including the whales huge heart. This exhibit is in 40 different countries. If you get a chance GO!
